[0042] The present embodiment provides a refrigerator 10. In the following description, the directions or positional relationships indicated by "front", "rear", "up", "down", "left", "right", etc. are directions or positional relationships based on the refrigerator 10 itself as a reference. Figure 6 The direction indicated, such as Figure 1 As shown, “horizontal” refers to a direction parallel to the width direction of the refrigerator 10 , “left” refers to the horizontal left side of the refrigerator with reference to the refrigerator 10 , and “right” refers to the horizontal right side of the refrigerator with reference to the refrigerator 10 .

[0043] Figure 1 is a schematic front view of a refrigerator 10 according to one embodiment of the present invention. Figure 2 yes Figure 1 A schematic three-dimensional diagram of a refrigerator 10 is shown. The refrigerator 10 may generally include a body 100, the body 100 includes an outer shell 110 and a storage liner arranged inside the outer shell 110, and the space between the outer shell 110 and the storage liner is filled with a heat-insulating material (forming a foaming layer). A storage compartment is defined in the storage liner, and the storage liner may generally include a freezing liner 130, a variable temperature liner 131, a refrigerating liner 120, etc. The storage compartment includes a freezing chamber 132 defined by the freezing liner 130, and a refrigerating chamber 121 defined by the refrigerating liner 120. A variable temperature chamber 1311 is defined in the variable temperature liner 131. A door body is also provided on the front side of the storage liner to open or close the storage compartment, Figure 1 , Figure 2 The door body is hidden in the middle.

[0044] As can be appreciated by those skilled in the art, the refrigerator 10 of this embodiment may further include an evaporator 101, an air supply fan (not shown), a compressor 104, a condenser 105, and a throttling element (not shown), etc. The evaporator 101 is connected to the compressor 104, the condenser 105, and the throttling element via a refrigerant pipeline to form a refrigeration cycle, and the temperature is reduced when the compressor 104 is started to cool the air flowing through it. In this embodiment, the freezing liner 130 is located at the lower part of the box body 100, and a cooling chamber 200 located at the bottom is defined therein. The evaporator 101 is arranged in the cooling chamber 200 to cool the airflow entering the cooling chamber 200, and the freezing chamber 132 defined by the freezing liner 130 is located above the cooling chamber 200, so that the cooling chamber 200 is at the lowest part of the box body 100. Specifically, the evaporator 101 as a whole can be placed horizontally in the cooling chamber 200 in a flat cubic shape, that is, the length and width of the evaporator 101 are parallel to the horizontal plane, the thickness is placed perpendicular to the horizontal plane, and the thickness dimension is significantly smaller than the length dimension of the evaporator 101. By placing the evaporator 101 horizontally in the cooling chamber 200, the evaporator 101 is prevented from occupying more space, and the storage volume of the freezing chamber 132 above the cooling chamber 200 is guaranteed. At least one front return air inlet connected to the freezing chamber 132 is formed on the front side of the cooling chamber 200, so that the return air flow of the freezing chamber 132 enters the cooling chamber 200 through the at least one front return air inlet and is cooled by the evaporator 101, thereby forming an air flow circulation between the cooling chamber 200 and the freezing chamber 132.

[0045] In a conventional refrigerator 10, the freezer compartment 132 is located at the bottom of the refrigerator 10, and the compressor compartment 300 is located at the rear of the freezer compartment 132. The freezer compartment 132 inevitably has to be made into an irregular space to make room for the compressor compartment 300, which reduces the storage capacity of the freezer compartment 132 and also brings about the following problems. On the one hand, the freezer compartment 132 is located at a relatively low position, and the user needs to bend over or squat significantly to take and put items in the freezer compartment 132, which is inconvenient for users, especially for the elderly. On the other hand, since the depth of the freezer compartment 132 is reduced, in order to ensure the storage volume of the freezer compartment 132, the space in the height direction of the freezer compartment 132 needs to be increased. When the user stores items in the freezer compartment 132, the items need to be stacked in the height direction, which is inconvenient for the user to find items. In addition, the items at the bottom of the freezer compartment 132 are easily blocked, making it difficult for the user to find them and forget them, resulting in deterioration and waste of the items. Furthermore, since the freezer compartment 132 is of an irregular shape and not a rectangular space, it is inconvenient to place some large and difficult to divide items in the freezer compartment 132. The refrigerator 10 of this embodiment defines a cooling chamber 200 in the bottom space of the freezing liner 130, and defines a freezing chamber 132 above the cooling chamber 200, so that the cooling chamber 200 occupies the lower space in the freezing liner 130, raising the freezing chamber 132, reducing the degree of bending when the user takes and places items in the freezing chamber 132, and improving the user's experience. At the same time, the press cabin 300 can be located behind the cooling chamber 200, and the freezing chamber 132 does not need to make way for the press cabin 300, so that the freezing chamber 132 is a rectangular space, so that the items can be stored in a flat-laying manner instead of in a stacked manner, which is convenient for users to find items and saves users' time and energy; at the same time, it is also convenient to place large items that are not easy to divide, solving the pain point that large items cannot be placed in the freezing chamber 132.

[0046] In some embodiments, the air supply fan in the refrigerator 10 is disposed in the cooling chamber 200, and is configured to suck the return air flow into the cooling chamber 200 for cooling by the evaporator 101, and to promote the cooled air flow to flow toward the freezing chamber 132 and the variable temperature chamber 1311. The refrigerator 10 of this embodiment further includes a freezing chamber air supply duct 141 and a variable temperature chamber air supply duct 1312. The freezing chamber air supply duct 141 is connected to the air outlet end of the air supply fan, and is configured to transport part of the air flow cooled by the evaporator 101 to the freezing chamber 132. The freezing chamber air supply duct 141 is disposed on the inner side of the rear wall of the freezing liner 130, and has a plurality of air supply outlets 141a connected to the freezing chamber 132.

[0047] Figure 3 yes Figure 1Schematic stereogram of some parts of the refrigerator 10 shown. In some embodiments, the refrigerator 10 also includes a cover plate 102, the cover plate 102 includes a top cover 1021 located above the evaporator and at least one front cover group 1020, the front side of each front cover group 1020 is formed with the aforementioned at least one front return air inlet, the top cover 1021, the at least one front cover group 1020 and the rear wall, bottom wall and two lateral side walls of the freezing liner 130 together define the cooling chamber 200, and accordingly, the lateral side wall of the freezing liner 130 constitutes the lateral side wall of the cooling chamber 200. In this embodiment, there are two front cover groups 1020, and the two front cover groups 1020 are distributed in the lateral direction. In this embodiment, the refrigerator 10 also includes a vertical partition plate (not shown), which extends downward from the top wall of the freezing liner 130 to the upper surface of the top cover 1021 to separate the freezing chamber 132 into two refrigeration spaces distributed laterally. The air duct front cover plate of the freezer compartment air supply duct 141 is formed with a mounting groove 141c that cooperates with the vertical partition plate. In this embodiment, the two front cover groups 1020 are spaced apart in the lateral direction, and the vertical partition plate includes a front shielding portion extending between the two front cover groups 1020 and located in front of the evaporator 101 to shield the gap between the two front cover groups 1020, thereby completely isolating the airflow in the two freezing spaces of the freezer compartment 132, so that the return air of the freezing space located on the right side in the lateral direction enters the cooling chamber 200 through the front return air inlet of the front cover group 1020 located on the right side in the lateral direction, and the return air of the freezing space located on the left side in the lateral direction enters the cooling chamber 200 through the front return air inlet of the front cover group 1020 located on the left side in the lateral direction.

[0048] Figure 4 yes Figure 3 The schematic exploded view of some components of the refrigerator 10 is shown. Two front return air inlets are formed on the front side of each front cover group 1020, and the two front return air inlets are respectively marked as a first front return air inlet 102a and a second front return air inlet 102b. Each front cover group 1020 includes a front decorative cover 1022 and a front air duct cover 1023, the front end portion 10221 of the front decorative cover 1022 is located in front of the front end of the evaporator 101, the front end portion 10221 is spaced from the front end of the evaporator 101, the front wall of the front end portion 10221 of the front decorative cover 1022 is formed with a first opening 1022a, and the rear side of the front end portion 10221 of the front decorative cover 1022 is open; the front end portion 10231 of the front air duct cover 1023 is located at the front end of the evaporator 101, and the front end portion 10231 of the front air duct cover 1023 is inserted forwardly into the front decorative cover 1022 from the rear opening of the front end portion 10221 of the front decorative cover 1022, so as to separate the first opening 1022a into a first front return air inlet 102a located below and a second front return air inlet 102b located above.

[0049] Specifically, the bottom wall of the front end portion 10231 of the front air duct cover 1023 and the bottom wall of the front end portion 10221 of the front decorative cover 1022 define a first return air channel that is connected to the first front return air inlet 102a, and the first return air channel is located in front of the evaporator 101. That is to say, the front end portion 10231 of the front air duct cover 1023 is inserted forward into the front decorative cover 1022 from the rear side opening of the front end portion 10221 of the front decorative cover 1022 so that the bottom wall of the front end portion 10231 of the front air duct cover 1023 and the bottom wall of the front end portion 10221 of the front decorative cover 1022 are spaced apart to form a first return air channel that is connected to the first front return air inlet 102a, so that at least part of the return air flow entering the first return air channel through the first front return air inlet 102a enters the evaporator 101 from the front of the evaporator 101 and is cooled by the evaporator 101. The front end portion 10231 of the front air duct cover 1023 is formed with a second opening 1023a that is connected to the second front return air inlet 102b in the upper section, and the second opening 1023a is located in the upper front of the evaporator 101. The lower surface of the top cover 1021 is spaced apart from the upper surface of the evaporator 101, and the front end of the top cover 1021 is located above the rear of the front end of the evaporator 101, that is, the top cover 1021 does not completely cover the upper surface of the evaporator 101. In addition, a windshield material (not shown) is filled between the lower surface of the top cover 1021 and the upper surface of the evaporator 101, and the top cover 1021 and the upper surface of the evaporator 101 are spaced apart to form a spacing space 102c, and the spacing space 102c is filled with a windshield material, which can be a windshield foam. In addition, the front air duct cover 1023 includes a first shielding portion 10232 located above and behind the second opening 1023a, and the rear end of the first shielding portion 10232 abuts against the front end of the top cover 1021 to close the portion above the upper surface of the evaporator 101 that is not shielded by the top cover 1021, thereby forming a second return air channel that passes through the second opening 1023a and the second front return air inlet 102b between the first shielding portion 10232 and the upper surface of the evaporator 101, so that at least part of the return air flow that enters the second return air channel through the second front return air inlet 102b enters the evaporator 101 from above the evaporator 101 and is cooled by the evaporator. Since the space 102c between the top cover 1021 and the upper surface of the evaporator 101 is filled with wind-blocking material, the return air flow entering the second return air channel is prevented from flowing directly backwards without passing through the evaporator 101, so that the return air flow entering the second return air channel flows downward and enters the evaporator 101 from the upper surface of the evaporator 101.The front decorative cover 1022 includes a second shielding portion 10222 that is bent and extended rearward and upward from the upper rear edge of the front end portion 10221 thereof, and the second shielding portion 10222 is located above the first shielding portion 10232 and extends to overlap with the upper surface of the top cover 1021 so as to completely shield the upper part of the first shielding portion 10232, and the shape of the second shielding portion 10222 is adapted to the shape of the first shielding portion 10232 so that the second shielding portion 10222 and the first shielding portion 10232 fit closely together to avoid air leakage.

[0050] Since the temperature around the front end surface of the evaporator 101 is significantly different from the temperature of the return air flow, frost is easily formed on the front end surface of the evaporator 101 . If the front end surface of the evaporator 101 is not frosted or the amount of frost is small so that the front end surface of the evaporator 101 can still pass air flow, then a part of the return air flow of the freezer chamber 132 enters the first return air channel through the first front return air inlet 102a, and a part of the return air flow of the freezer chamber enters the second return air channel through the second front return air inlet 102b. Part of the airflow entering the first return air channel enters the evaporator 101 from the front of the evaporator 101 (that is, from the front end surface of the evaporator 101), and is cooled by the evaporator 101. Another part of the airflow entering the first return air channel flows upward to the second return air channel, and then flows downward from the second return air channel into the evaporator 101, so that part of the return air flow enters the evaporator 101 from the front of the evaporator 101, and part of the return air flow enters the evaporator 101 from above the evaporator 101, thereby ensuring sufficient heat exchange between the return air flow and the evaporator 101, thereby improving the refrigeration effect of the refrigerator 10. If the front surface of the evaporator 101 is frosted thickly and the airflow cannot enter the evaporator 101, the return airflow of the freezing chamber 132 can enter the second return air channel through the second front return air inlet 102b located above, and flow downward from the second return air channel to the upper surface of the evaporator 101 and enter the evaporator 101 for cooling, thereby still ensuring the refrigeration effect of the refrigerator 10. The refrigerator 10 of this embodiment ensures the heat exchange efficiency between the return airflow of the freezing chamber 132 and the evaporator 101 by specially designing the structures of the top cover 1021, the front decorative cover 1022 and the front air duct cover 1023, thereby improving the refrigeration effect of the refrigerator 10. In addition, when the front surface of the evaporator 101 is frosted, it can still be ensured that the return airflow can enter the evaporator 101 and be cooled by the evaporator 101, thereby solving the problem of reduced refrigeration effect of the existing refrigerator 10 due to frosting of the evaporator 101 and improving the overall performance of the refrigerator 10.

[0051] In the refrigerator 10 of the present embodiment, the refrigeration liner 120 is located above the temperature-variable liner 131, and a refrigeration chamber 121 is defined in the refrigeration liner 120. The refrigerator 10 of the present embodiment further includes a refrigeration evaporator (not shown), a refrigeration fan (not shown), and a refrigeration air supply duct (not shown). A refrigeration evaporator chamber is defined at the lower inner side of the rear wall of the refrigeration liner 120, and the refrigeration evaporator and the refrigeration fan are arranged in the refrigeration evaporator chamber. The refrigeration air supply duct is arranged at the inner side of the rear wall of the refrigeration liner 120, and has a refrigeration air supply inlet connected to the air outlet end of the refrigeration fan and a refrigeration air supply outlet connected to the refrigeration chamber 121. The refrigeration fan is configured to cause the air flow cooled by the refrigeration evaporator to flow into the refrigeration chamber 121 through the refrigeration air supply duct to adjust the temperature of the refrigeration chamber 121. At least one refrigerated return air inlet is formed on the front side of the refrigerated evaporator chamber to guide the return air flow of the refrigerated chamber 121 to the refrigerated evaporator chamber through the refrigerated return air inlet to be cooled by the refrigerated evaporator, thereby forming an air flow circulation between the refrigerated chamber 121 and the refrigerated evaporator chamber.

[0052] As is well known to those skilled in the art, the temperature in the refrigerator 121 is generally between 2°C and 10°C, preferably between 4°C and 7°C. The temperature in the freezer 132 is generally between -22°C and -14°C. The temperature of the variable temperature chamber 1311 can be adjusted to -18°C to 8°C at will. Different types of items have different optimal storage temperatures and different suitable storage locations. For example, fruit and vegetable foods are suitable for storage in the refrigerator 121, while meat foods are suitable for storage in the freezer 132.

[0053] Figure 5 yes Figure 1 A partial schematic cross-sectional view of a refrigerator 10 is shown. Figure 6 yes Figure 1 A schematic exploded view of a compressor compartment 300 of a refrigerator 10 is shown. Figure 7 yes Figure 6 A schematic partial enlarged schematic diagram of . Figure 8 yes Figure 6 A schematic bottom view of the compressor cabin 300 of the refrigerator 10 is shown. The compressor cabin 300 is defined at the bottom of the housing 100, and the compressor cabin 300 is located behind the cooling chamber 200, so that the compressor cabin 300 is located below the freezing chamber 132 as a whole. As mentioned above, the freezing chamber 132 does not need to make way for the compressor cabin 300, which ensures the depth of the freezing chamber 132 and is convenient for placing large and difficult to divide items. The refrigerator 10 also includes a heat dissipation fan 106. The heat dissipation fan 106 can be an axial flow fan. The compressor 104, the heat dissipation fan 106 and the condenser 105 are arranged in the compressor cabin 300 in sequence along the horizontal direction.

[0054] In some embodiments, at least one rear air outlet 1162 a is formed in a section 1162 of the rear wall of the compressor cabin 300 corresponding to the compressor 104 .

[0055] In fact, before the present invention, the general design idea of ​​those skilled in the art is to open a rear air inlet facing the condenser 105 and a rear air outlet 1162a facing the compressor 104 on the rear wall of the compressor cabin 300, so as to complete the circulation of the heat dissipation airflow at the rear of the compressor cabin 300; or to form ventilation holes on the front wall and the rear wall of the compressor cabin 300, respectively, to form a heat dissipation circulation air path in the front-to-back direction. When faced with the problem of improving the heat dissipation effect of the compressor cabin 300, those skilled in the art usually increase the number of the rear air inlet and rear air outlet 1162a on the rear wall of the compressor cabin 300 to expand the ventilation area, or increase the heat exchange area of ​​the condenser 105, such as using a U-shaped condenser with a larger heat exchange area.

[0056] However, the applicant creatively realized that the larger the heat exchange area of ​​the condenser 105 and the ventilation area of ​​the compressor cabin 300, the better. In the conventional design scheme of increasing the heat exchange area of ​​the condenser 105 and the ventilation area of ​​the compressor cabin 300, the problem of uneven heat dissipation of the condenser 105 will be brought about, which will have an adverse effect on the refrigeration system of the refrigerator 10. To this end, the applicant breaks away from the conventional design ideas and creatively proposes a new scheme different from the conventional design. The bottom wall of the box body is defined with a bottom air inlet 110a adjacent to the condenser 105 and a bottom air outlet 110b adjacent to the compressor 104, and the circulation of the heat dissipation airflow is completed at the bottom of the refrigerator 10, making full use of the space between the refrigerator 10 and the supporting surface. There is no need to increase the distance between the back wall of the refrigerator 10 and the cabinet. While reducing the space occupied by the refrigerator 10, it ensures good heat dissipation of the compressor cabin 300, fundamentally solving the pain point that the heat dissipation and space occupation of the compressor cabin 300 of the embedded refrigerator 10 cannot be balanced, which is of particular significance. Support rollers 900 may also be provided at the four corners of the bottom wall of the box body 100 . The box body 100 is placed on the support surface via the four support rollers 900 , and a certain space is formed between the bottom wall of the box body 100 and the support surface.

[0057] The heat dissipation fan 106 is configured to force the ambient air around the bottom air inlet 110a to enter the compressor cabin 300 from the bottom air inlet 110a, and pass through the condenser 105 and the compressor 104 in sequence, and then flow to the external environment from the bottom air outlet 110b to dissipate heat from the compressor 104 and the condenser 105. In the vapor compression refrigeration cycle, the surface temperature of the condenser 105 is generally lower than the surface temperature of the compressor 104, so in the above process, the external air first cools the condenser 105 and then cools the compressor 104.

[0058] In a preferred embodiment, the plate section 1161 of the back plate 116 (the rear wall of the compressor cabin 300) facing the condenser 105 is a continuous plate surface, that is, there is no heat dissipation hole on the plate section 1161 of the back plate 116 facing the condenser 105. The applicant creatively realized that even without increasing the heat exchange area of ​​the condenser 105, the abnormal reduction of the ventilation area of ​​the compressor cabin 300 can form a better heat dissipation airflow path, and still achieve a better heat dissipation effect. In the preferred embodiment of the present invention, the applicant breaks through the conventional design ideas and designs the plate section 1161 corresponding to the rear wall (back plate 116) of the compressor cabin 300 and the condenser 105 as a continuous plate surface, and the heat dissipation airflow entering the compressor cabin 300 is sealed at the condenser 105, so that the ambient air entering from the bottom air inlet 110a is more concentrated at the condenser 105, ensuring the heat exchange uniformity of each condensation section of the condenser 105, and is conducive to forming a better heat dissipation airflow path, which can also achieve a better heat dissipation effect. Furthermore, since the plate section 1161 of the back plate 116 facing the condenser 105 is a continuous plate surface without an air inlet, it avoids the situation in the conventional design where both the air outlet and the air inlet are concentrated at the rear of the compressor cabin 300, resulting in the hot air blown out from the compressor cabin 300 not being cooled by the ambient air in time and re-entering the compressor cabin 300, which has an adverse effect on the heat exchange of the condenser 105, thereby ensuring the heat exchange efficiency of the condenser 105.

[0059] In some embodiments, the two lateral side walls of the compressor cabin 300 are each formed with a side vent, which may be covered with a vent cover 108, and the vent cover 108 is formed with grille-type vent holes. The outer shell of the refrigerator 10 includes two lateral box side panels 111, which extend vertically to form two side walls of the refrigerator 10, and the two box side panels 111 respectively form a side opening 111a connected to the corresponding side vent, so that the heat dissipation airflow flows to the outside of the refrigerator 10. This further increases the heat dissipation path and ensures the heat dissipation effect of the compressor cabin 300.

[0060] In some embodiments, the condenser 105 includes a first straight section 1051 extending transversely, a second straight section 1052 extending forward and backward, and a transition curved section (not numbered) connecting the first straight section 1051 and the second straight section 1052, thereby forming an L-shaped condenser 105 with an appropriate heat exchange area. The plate section 1161 corresponding to the rear wall (back plate 116) of the aforementioned compressor cabin 300 and the condenser 105 is also the plate section 1161 of the back plate 116 facing the first straight section 1051. The ambient airflow entering from the side vents directly exchanges heat with the second straight section 1052, and the ambient air entering from the bottom air inlet 110a directly exchanges heat with the first straight section 1051, thereby further concentrating more ambient air entering the compressor cabin 300 at the condenser 105, ensuring the uniformity of the overall heat dissipation of the condenser 105.

[0061] The box body 100 further includes a special-shaped plate 400, a support plate 112 and two side plates 119. The special-shaped plate 400 includes a bottom horizontal section 113 located at the front side of the bottom and a bent section 401 bent and extended from the rear end of the bottom horizontal section 113 to the rear and upward, and the bent section 401 extends to the top of the support plate 112. The support plate 112 and the bottom horizontal section 113 together constitute the bottom wall of the box body 100. The two side plates 119 extend upward from the two lateral sides of the support plate 112 to the two lateral sides of the bent section 401 to close the two lateral sides of the press chamber 300 and constitute the two lateral side walls of the press chamber 300. The back plate 116 extends upward from the rear end of the support plate 112 to the rear end of the bent section 401 and constitutes the rear wall of the press chamber 300.

[0062] Fig.10 yes Figure 6 Schematic stereogram of the support plate 112 of the refrigerator 10 shown. Specifically, the support plate 112 includes a first section 1121 and a second section 1122 extending forward from the front end of the first section 1121. The compressor 104, the heat dissipation fan 106 and the condenser 105 are arranged in the first section 1121 of the support plate 112 in sequence in the horizontal direction, and are located in the space defined by the support plate 112, the two side panels 119, the back panel 116 and the bending section 401. The front end of the second section 1122 is connected to the bottom horizontal section 113, and the upper side thereof is provided with the aforementioned bottom air inlet 110a at a side adjacent to the condenser 105 and the aforementioned bottom air outlet 110b at a side adjacent to the compressor 104. In an embodiment of the present invention, the support plate 112 and the special-shaped plate 400 are arranged so that the support plate 112 and the bottom horizontal section 113 together constitute the bottom wall of the box body 100, and a bottom air inlet 110a and a bottom air outlet 110b are arranged at the front end portion of the support plate 112. The bottom air inlet 110a and the bottom air outlet 110b are respectively composed of a plurality of ventilation holes, which can make the refrigerator 10 rodent-proof. At the same time, this structure can greatly simplify the installation process of the refrigerator 10. It is only necessary to integrate the compressor 104, the heat dissipation fan 106 and the condenser 105 on the support plate 112, and then integrate the support plate 112 and the special-shaped plate 400 to complete the installation of the bottom wall of the box body 100.

[0063] Fig.11 yes Fig.10 A schematic side view of the tray 112 of the refrigerator 10 is shown. In some embodiments, the first section 1121 is disposed substantially horizontally; and the second section 1122 is disposed substantially horizontally.

[0064] Fig.121 is a schematic side view of a support plate 112 of a refrigerator 10 according to another embodiment of the present invention. In other embodiments, the first section 1121 is horizontally arranged; the second section 1122 has a first portion 11221 and a second portion 11222, the first portion 11221 is formed by extending forward and upward from the front end of the first section 1121, and the second portion 11222 is formed by extending forward and downward from the front end of the first portion 11221. In a preferred embodiment, the angle between the first portion 11221 and the horizontal plane is less than 45°. In a more preferred embodiment, the angle between the first portion 11221 and the horizontal plane is 20°-30°.

[0065] In some embodiments, the bending section 401 includes a first inclined section 1131, a second inclined section 114, a third inclined section 402, and a top horizontal section 115. The first inclined section 1131 extends upward from the rear end of the bottom horizontal section 113, the second inclined section 114 extends backward and upward from the upper end of the first inclined section 1131, the third inclined section 402 extends backward and upward from the upper end of the second inclined section 114, and the top horizontal section 115 extends backward from the upper end of the third inclined section 402 to the back plate 116 to shield the compressor 104, the heat dissipation fan 106, and the upper part of the condenser 105. In particular, the applicant creatively realized that the slope structure of the bending section 401 can guide and rectify the incoming air flow, so that the air flow entering from the bottom air inlet 110a can flow to the condenser 105 more concentratedly, avoiding the air flow being too dispersed and unable to pass through the condenser 105 more, thereby further ensuring the heat dissipation effect of the condenser 105; at the same time, the slope structure of the bending section 401 guides the outlet air flow of the bottom air outlet 110b to the front side of the bottom air outlet, so that the outlet air flow can flow out of the compressor chamber 300 more smoothly, thereby further improving the smoothness of the air flow.

[0066] In a preferred embodiment, the angle between the first inclined section 1131 and the horizontal plane is slightly less than 90°, and the angle between the second inclined section 114 and the third inclined section 402 and the horizontal plane is less than 45°. In this embodiment, the slope structure of the bending section 401 has a better effect on guiding and rectifying the airflow. In addition, surprisingly, the applicant creatively realized that the slope structure of the bending section 401 has a better effect on suppressing the airflow noise. In the prototype test, the noise of the compressor cabin 300 with the above specially designed slope structure can be reduced by more than 0.65 decibels.

[0067] In addition, the bottom of the box 100 of the conventional refrigerator 10 is generally an integrated bearing plate with a roughly flat structure, and the compressor 104 is arranged on the inner side of the bearing plate. The vibration generated by the compressor 104 during operation has a greater impact on the bottom of the box 100. In this embodiment, as mentioned above, the bottom of the box 100 is constructed into a three-dimensional structure by a special-shaped plate 400 and a support plate 112 of a special structure, providing an independent three-dimensional space for the arrangement of the compressor 104, and the support plate 112 is used to carry the compressor 104, thereby reducing the impact of the vibration of the compressor 104 on other components at the bottom of the box 100. In addition, by designing the box 100 as the above-mentioned ingenious special structure, the structure of the bottom of the refrigerator 10 is compact and the layout is reasonable, which reduces the overall volume of the refrigerator 10, and at the same time fully utilizes the space at the bottom of the refrigerator 10, ensuring the heat dissipation efficiency of the compressor 104 and the condenser 105.

[0068] Fig. 9 yes Figure 6 A schematic top view of the compressor compartment 300 of the refrigerator 10 is shown. In some embodiments, there is a gap between the front end surface of the condenser 105 and the bottom air inlet 110a. When the position of the heat dissipation air inlet remains unchanged, it means that the condenser 105 is moved backward. Those skilled in the art will conventionally arrange the condenser 105 as close to the heat dissipation air inlet as possible in the front-to-back direction to save space. However, the applicant creatively realized that moving the condenser 105 backward can allow the size of the condenser 105 to be appropriately reduced, thereby saving more space.

[0069] In some embodiments, the distance L between the front end surface of the condenser 105 and the bottom air inlet 110a is not less than 10 cm, preferably 10-50 cm. The refrigerator 10 of the embodiment of the present invention sets a specific distance between the front end surface of the condenser 105 and the bottom air inlet 110a, which can reduce the turbulence of the incoming air and reduce the resistance of the incoming air, which not only increases the amount of incoming air, but also reduces the noise of the incoming air flow.

[0070] In some embodiments, the evaporating dish 600 of the refrigerator 10 is a roughly rectangular parallelepiped structure with an opening at the top, and has a bottom wall and four side walls extending upward from the bottom wall. Support blocks 620 are respectively provided on the bottom wall of the evaporating dish 600 corresponding to the first straight section 1051 and the second straight section 1052 of the condenser 105. Fig. 9As shown, two support blocks 620 are arranged at intervals along the horizontal direction on the bottom wall of the evaporating dish 600, and one support block 620 is arranged along the vertical direction on the bottom wall of the evaporating dish 600. The condenser 105 is provided with a support member 1053 at its bottom, and the condenser 105 is fixed in the evaporating dish 600 by fixing the support member 1053 with the support block 620, so that the bottom end of the condenser 105 is higher than the top of the front wall of the evaporating dish 600. By raising the height of the condenser 105 in the evaporating dish 600, the bottom of the condenser 105 is also exposed to the external airflow, and the heat dissipation effect of the condenser 105 is further ensured.

[0071] Fig.13 yes Figure 6 A schematic top view of some components of the compressor compartment 300 of the refrigerator 10 is shown. In some embodiments, the refrigerator 10 further includes a partition 117, which is configured to completely isolate the bottom air inlet 110a and the bottom air outlet 110b, so as to allow external air to enter the compressor compartment 300 through the bottom air inlet 110a located on one lateral side of the partition 117 under the action of the heat dissipation fan 106, and flow through the condenser 105 and the compressor 104 in sequence, and finally flow out from the bottom air outlet 110b located on the other lateral side of the partition 117, so that the external air entering the condenser 105 and the heat dissipation air discharged from the compressor 104 will not flow in series.

[0072] In some embodiments, the refrigerator 10 further includes a fan fixing frame 500. The fan fixing frame 500 is fixed in the compressor cabin 300 along the front-to-back direction, and is used to fix the heat dissipation fan 106. The partition 117 is fixed to the fan fixing frame 500, which can ensure the installation stability of the partition 117 on the one hand, and reduce the noise generated by the vibration of the heat dissipation fan 106 on the other hand.

[0073] In some embodiments, the partition 117 is also fixed to the evaporation dish 600 , which can further enhance the installation stability of the partition 117 .

[0074] In a preferred embodiment, the partition 117 is disposed behind the bending section 401 , with its front portion connected to the rear end of the bottom horizontal section 113 , and its rear portion fixed to the fan fixing frame 500 and the evaporation dish 600 , respectively.

[0075] Fig.14 yes Fig.13 Schematic cross-sectional view along line AA. Fig.15 yes Fig.13 Schematic cross-sectional view along line BB. Fig.16 yes Figure 6The schematic three-dimensional diagram of the partition 117 of the refrigerator 10 shown. The partition 117 has a first partition 901, a second partition 902 and a bottom connecting portion 903 therebetween. The rear portion 911 of the first partition 901 includes a main body 9113, a first convex rib 9111 and a second convex rib 9112. The main body 9113 is provided with a receiving groove 9114. The first convex rib 9111 and the second convex rib 9112 extend backward from the left and right sides of the rear end of the main body 9113 respectively. The front portion of the fan fixing frame 500 is clamped between the first convex rib 9111 and the second convex rib 9112. The fan fixing frame 500 has a protrusion 510 extending forward at its front end. The protrusion 510 of the fan fixing frame 500 fits in the receiving groove 9114 to achieve the clamping fixation of the partition 117 and the fan fixing frame 500. The rear portion 921 of the second partition 902 includes a main body 9212 and a ridge 9211 extending backward from one side of the main body 9212 close to the evaporating dish 600. The lower portion of the main body 9212 is recessed forward to form a horizontal abutting surface 9213. The evaporating dish 600 has a protrusion 610 extending forward from its front wall. The protrusion 610 of the evaporating dish 600 fits under the horizontal abutting surface 9213 to achieve abutment and fixation of the partition 117 and the evaporating dish 600.

[0076] A plurality of claws 930 are further extended downwardly from the bottom connection portion 903 , and the support plate 112 is provided with holes at corresponding positions thereof. The partition 117 is fixed to the support plate 112 by fixing the claws 930 in the holes.

[0077] When there is a gap between the front end face of the condenser 105 and the bottom air inlet 110a, there is also a gap between the partition 117 and the evaporation dish 600. The partition 117 can be completely isolated from the bottom air inlet 110a and the bottom air outlet 110b by setting a baffle 800 at the gap. In one embodiment, a baffle 800 is set between the rear portion 921 of the second partition 902 and the first straight section 1051 of the condenser 105. The baffle 800 can be an integral part or a split assembly, as long as it can cover the gap between the front end face of the condenser 105 and the partition 117.

[0078] In addition, a gap 904 is formed between the first partition 901, the second partition 902, and the bottom connecting portion 903 to provide a space for the water pipe 700 of the refrigerator 10 to be connected to the evaporation dish 600. In the present application, the partition 117 is preferably an integrally molded plastic part, which can simplify the production process and installation process of the partition 117.

[0079] In some embodiments, the upper end of the condenser 105, the upper end of the fan bracket 500, and the upper end of the partition 117 are also provided with wind shields 1056. The wind shields 1056 can be wind shield sponges, which fill the spaces between the upper end of the condenser 105, the upper end of the fan bracket 500, the upper end of the partition 117 and the bending section 401. Specifically, for the condenser 105, the windshield 1056 covers the upper ends of the first straight section 1051, the second straight section 1052 and the transition curved section, and the upper end of the windshield 1056 abuts against the inner surface of the bent section 401 to seal the upper end of the condenser 105, so as to prevent part of the air entering the compressor cabin 300 from passing through the space between the upper end of the condenser 105 and the bent section 401 instead of passing through the condenser 105, so that the air entering the compressor cabin 300 can pass through the condenser 105 as much as possible for heat exchange, further improving the heat dissipation effect of the condenser 105. For the fan fixing frame 500, the windshield 1056 covers the upper end of the fan fixing frame 500, and the upper end of the windshield 1056 abuts against the inner surface of the bent section 401. For the partition 117 portion, the wind shield 1056 covers the upper ends of the first partition 901 and the second partition 902 , and the upper end of the wind shield 1056 abuts against the inner surface of the bending section 401 .

[0080] In some embodiments, the refrigerator 10 also includes a wind shield 107 extending forward and backward, and the wind shield 107 is located between the bottom air inlet 110a and the bottom air outlet 110b, extending from the lower surface of the bottom horizontal section 113 to the lower surface of the support plate 112, so that when the refrigerator 10 is placed on a support surface, the space between the bottom wall of the box body 100 and the support surface is transversely divided to allow external air to enter the compressor compartment 300 through the bottom air inlet 110a located on the lateral side of the wind shield 107 under the action of the heat dissipation fan 106, and flow through the condenser 105 and the compressor 104 in turn, and finally flow out from the bottom air outlet 110b located on the other lateral side of the wind shield 107, thereby completely isolating the bottom air inlet 110a and the bottom air outlet 110b, ensuring that the external air entering the condenser 105 and the heat dissipation air discharged from the compressor 104 will not flow in parallel, further ensuring the heat dissipation efficiency.

[0081] The refrigerator 10 of the embodiment of the present invention defines a cooling chamber 200 at the bottom and a freezing chamber 132 above the cooling chamber 200, so that the cooling chamber 200 occupies the lower space in the freezing liner 130, raises the freezing chamber 132, reduces the degree of bending when the user takes and places items in the freezing chamber 132, and improves the user's experience. In addition, by providing a partition 117, the bottom air inlet 110a and the bottom air outlet 110b are completely isolated, so that the external air entering the condenser 105 and the heat dissipation air discharged from the compressor 104 will not flow in series.

[0082] Furthermore, the partition 117 of the refrigerator 10 of the embodiment of the present invention is fixed to the fan fixing frame 500, which can ensure the installation stability of the partition 117 on the one hand, and reduce the noise generated by the vibration of the heat dissipation fan 106 on the other hand.

[0083] Furthermore, the partition 117 of the refrigerator 10 according to the embodiment of the present invention is also fixed to the evaporating dish 600 and the support plate 112, so the installation is convenient and stable.

[0084] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived based on the content disclosed in the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all these other variations or modifications.
